| Abstract
|
| [Objective] To compare the component of chemical components and antioxidative activities of fresh and dried Denelrobium nobile Lindl., understand the difference of them, and provide reference for reasonable application of Denelrobium nobile Lindl. [Methods] GC-MS and UV spectrophotometry was carried out for chemical components analysis;the salicylic acid colorimetry and kit assay were used for determination of the scavenging effects on hydroxyl radical and TAC, respectively;the Fingerprint Features of Denelrobium nobile Lindl. were studied by Fourier Transform Infrared Spectroscopy(FT-IR). [Results] We found the content of total alkaloids, polysaccharide and hydroxyl radical and total antioxidant capacity in fresh Denelrobium nobile Lindl were significantly higher than dried one. There were some similarity infrared spectrum features for both Denelrobium nobile Lindl. At1 630 cm-1,1 506 cm-1,and 1 243 cm-1, the peak height of fresh Denelrobium nobile Lindl. was higher than dried Denelrobium nobile Lindl. in Guandu,Changqi, Honghua plantation base of Guizhou province. The infrared correlation coefficient with polysaccharide reference spectrum of the fresh Denelrobium nobile Lindl. was higher than dried one in all origins. [Conclusion] There is a certain difference in the component of chemical components and antioxidative activities in fresh Denelrobium nobile Lindl. and dried one. |
